CHAPTER II.

THE TURNING POINT.

"And Nature, the old nurse, took

The child upon her knee,

Saying: 'Here is a story-book

Thy Father has written for thee.'

'Come, wander with me,' she said,

'Into regions yet untrod;

And read what is still unread

In the manuscripts of God!'"

LONGFELLOW.

There is a story told of Sir Humphry Davy, that, on being asked on

a certain occasion to enumerate what he considered as his greatest

discoveries, he named first one thing and then another,--now his

wonderful safety-lamp, then some electrical discovery, finishing up

with "but the greatest of all my discoveries was the discovery of

Michael Faraday."

In the autumn of 1812, as we have seen, Faraday was a bookbinder, whose

apprenticeship was just at an end, and who was contemplating, as the

only thing possible, the taking up of life as a journeyman at the craft

at which for seven years he had been working; indeed, a journeyman

bookbinder he became, for in October of that year he engaged himself

to a Mr. De la Roche, who, though a quick-tempered, passionate man,

seems to have really cared for Faraday, so much so, indeed, that he

said to him, "I have no child, and if you will stay with me you shall

have all I have when I am gone." But Michael was not thus to be tempted

from the path which he desired to tread, as he wrote afterwards to

Davy's biographer, "My desire to escape from trade, which I thought

vicious and selfish, and to enter into the service of science, which

I imagined made its pursuers amiable and liberal, induced me at last

to take the bold and simple step of writing to Sir H. Davy, expressing

my wishes and a hope that if an opportunity came in his way he would

favour my views; at the same time, I sent the notes I had taken of his

lectures."

Shortly after Sir Humphry received Faraday's application, speaking

to a friend--the honorary inspector of the models and apparatus--he

said, "Pepys, what am I to do? Here is a letter from a young man named

Faraday; he has been attending my lectures, and wants me to give him

employment at the Royal Institution. _What can I do?_"

"Do?" was Pepys' reply, "do? put him to wash bottles; if he is good

for anything, he will do it directly; if he refuses, he is good for

nothing."

"No, no," said Davy, "we must try him with something better than that."

Notwithstanding the fact that his similar application of some months

before to Sir Joseph Banks had met with no answer, Faraday, in his

desire to leave trade for science, had thus addressed another of

the leading men of the day. Davy's reply was "immediate, kind, and

favourable." It was this--

"_December 12th, 1812._

"To Mr. Faraday,

"Sir,--I am far from displeased with the proof you have given me of

your confidence, and which displays great zeal, power of memory, and

attention. I am obliged to go out of town, and shall not be settled

in town till the end of January; I will then see you at any time you

wish. It would gratify me to be of any service to you; I wish it may

be in my power.

"I am, Sir, your obedient humble servant,

"H. DAVY."

[Illustration: SIR HUMPHRY DAVY.]

The young bookbinder's delight on receiving the great and

kindly-natured man's note may easily be imagined, as also may his

anxiety for Davy's return. Five weeks, however, are soon passed, and

Michael duly met Sir Humphry "by the window which is nearest to the

corridor, in the ante-room to the theatre" at the Royal Institution.

Davy was much impressed by the sincerity and modesty of the applicant,

but yet advised him to continue at his bookbinding, going so far,

indeed, as to say that he would get the Royal Institution binding

for him, and would recommend him to his friends.[4] With this, for

the present, Faraday had to be content. He returned to his binding,

delighted that he had met and conversed with the greatest chemist of

his time, but still anxious for an opportunity to leave that trade

to which, as he had said, he was so averse, and to become wholly the

servant of that science to which he was so attached.

The change in his vocation was to come far more rapidly than he could

have anticipated. He was still living, at this time (early in 1813), at

18, Weymouth Street, and one night, not very long after his interview

with Davy, just as he was undressing to go to bed, there came a loud

knock at the front door. Michael went to the window to see if there

was any evidence as to whom the unwonted visitor might be. A carriage

was there, from which a footman had alighted and left a note for

"Mr. M. Faraday." It proved to be from Sir Humphry, who had already

an opportunity of serving the young enthusiast. The note requested

Michael to call on Davy the next morning. This he did, and learned that

an assistant in the laboratory of the Royal Institution was required

at once, the former assistant having been dismissed the day before.

Michael instantly expressed his willingness to accept the position; he

was to have twenty-five shillings a week salary, and two rooms at the

top of the Institution building.

It was not long before arrangements were all completed. A meeting of

the managers of the Institution was held on March 1st; the following

is entered in the minutes of that day's proceedings:--"Sir Humphry

Davy has the honour to inform the managers that he has found a person

who is desirous to occupy the situation in the Institution lately

filled by William Payne. His name is Michael Faraday. He is a youth of

twenty-two years of age. As far as Sir H. Davy has been able to observe

or ascertain, he appears well fitted for the situation. His habits seem

good, his disposition active and cheerful, and his manner intelligent.

He is willing to engage himself on the same terms as those given to

Mr. Payne at the time of quitting the Institution. _Resolved_:--That

Michael Faraday be engaged to fill the situation lately occupied by Mr.

Payne on the same terms."

The duties of the assistant were specified by the managers in the

following manner, his work being something other than the washing of

bottles, which Pepys had recommended. It is a fact, also, that Faraday,

almost from the commencement of his engagement, was concerned in more

important work than that herein particularised. He was "to attend and

assist the lecturers and professors in preparing for, and during,

lectures; when any instruments or apparatus may be required, to attend

to their careful removal from the model room or laboratory to the

lecture-room, and to clean and replace them after being used, reporting

to the manager such accidents as shall require repair, a constant diary

being kept by him for that purpose. That, in one day in each week, he

be employed in keeping clean the models in the repository, and that

all the instruments in the glass cases be cleaned and dusted at least

once within a month." As has been said, Faraday's work was almost from

the first of a higher nature; he is reported to have set in order the

mineralogical collection soon after his arrival.

But a very short while elapsed between Michael's appointment as

assistant and his taking up the duties of his post, for, on the 8th

of March, he writes to Abbott, dating his letter from his new home,

the two rooms at the top of the Institution. His letter tells us that

he was already concerned in the active duties of his post, as the

following passages show: "It is now about nine o'clock, and the thought

strikes me that the tongues are going both at Tatum's and at the

lecture in Bedford Street; but I fancy myself much better employed than

I should have been at the lecture at either of those places. Indeed, I

have heard one lecture already to-day, and had a finger in it (I can't

say a hand, for I did very little). It was by Mr. Powell on mechanics,

or rather, on rotatory motion, and was a pretty good lecture, but not

very fully attended.

"As I know you will feel a pleasure in hearing in what I have been or

shall be occupied, I will inform you that I have been employed to-day,

in part, in extracting the sugar from a portion of beetroot, and also

in making a compound of sulphur and carbon--a combination which has

lately occupied in a considerable degree the attention of chemists."

About a month after writing the letter of which the above forms a part,

Faraday again wrote to his friend Abbott, giving him an account of

some experiments, in which he had been assisting Sir Humphry Davy, on

"the detonating compound of chlorine and azote, and of four different

and strong explosions of the substance, explosions from which neither

he nor Davy had altogether escaped unhurt." "Of these," he says, "the

most terrible was when I was holding between my thumb and finger a

small tube containing 7-1/2 grains of the compound. My face was within

twelve inches of the tube; but I fortunately had on a glass mask. It

exploded by the slight heat of a small piece of cement that touched

the glass above half-an-inch from the substance, and on the outside.

The explosion was so rapid as to blow my hand open, bear off a part

of one nail, and has made my fingers so sore that I cannot yet use

them easily. The pieces of the tube were projected with such force

as to cut the glass face of the mask I had on." In the other three

experiments also they each of them got more or less cut about by the

explosion of the "terrible compound," as Faraday calls it, Davy,

indeed, in the last one, getting somewhat seriously cut.

He writes thus frequently to Abbott during the summer of 1813, giving

him in the later letters some well thought-out ideas on lectures and

lecturing, which we shall have occasion to glance at when we are

considering Faraday himself in the capacity of a lecturer,--one of

the most popular and yet truly scientific lecturers of any time. In

this year, his twenty-first, Faraday joined the City Philosophical

Society, which had been founded about five years earlier by Mr.

Tatum, at whose house the meetings were held. The Society consisted

of some thirty or forty individuals, "perhaps all in the humble or

moderate rank of life;" and certainly all of them anxious to improve

themselves and add to their knowledge of scientific subjects. Once a

week the members gathered together for mutual instruction; each member

opening the discussion in his turn by reading a paper of a literary

or philosophical nature, any member failing to do so at his proper

time being fined half-a-guinea. In addition, the members had what they

modestly called a "class book," but probably very like what we should

now call a manuscript magazine; in this each member wrote essays, and

the work was passed round from one to another.

Michael, it will be seen, was not neglecting any opportunity of

educating himself; as he had said in starting his correspondence with

Abbott, one of his objects was to improve himself in composition and to

acquire a clear and simple method of expressing that which he had to

say. Yet another method had he of furthering his self-education. In the

scanty notes which he wrote about his own life he says, "During this

spring (1813) Magrath and I established the mutual improvement plan,

and met at my rooms up in the attics of the Royal Institution, or at

Wood Street at his warehouse. It consisted, perhaps, of half-a-dozen

persons, chiefly from the City Philosophical Society, who met of an

evening to read together, and to criticise, correct, and improve each

other's pronunciation and construction of language. The discipline

was very sturdy, the remarks very plain and open, and the results

most valuable. This continued for several years." It is a matter for

wonder how Faraday, with all these attempts to improve his language and

method, and to avoid even the slightest peculiarity, managed yet to

retain in all his work a remarkable simplicity and naturalness of style.

On September 13, 1813, Faraday wrote to his uncle and aunt, giving

them an account of himself because he had nothing else to say, and was

asked by his mother to write the account:--"I was formerly a bookseller

and binder, but am how turned philosopher, which happened thus: Whilst

an apprentice, I, for amusement, learnt a little of chemistry and

other parts of philosophy, and felt an eager desire to proceed in

that way further. After being a journeyman for six months, under a

disagreeable master, I gave up my business, and, by the interest of Sir

Humphry Davy, filled the situation of chemical-assistant to the Royal

Institution of Great Britain, in which office I now remain, and where I

am constantly engaged in observing the works of nature and tracing the

manner in which she directs the arrangement and order of the world. I

have lately had proposals made to me by Sir Humphry Davy to accompany

him, in his travels through Europe and into Asia, as philosophical

assistant. If I go at all, I expect it will be in October next, about

the end, and my absence from home will perhaps be as long as three

years. But, as yet, all is uncertain, I have to repeat that, even

though I may go, my path will not pass near any of my relations, or

permit me to see those whom I so much long to see."

This Continental trip with Davy forms one of the chief episodes in

Faraday's life. He had, though two-and-twenty years of age, never

before been further than a few miles out of London. The country

through which he passed, the sea, and the mountains, all came to him

as a revelation. The letters which he wrote home from abroad, and

the journals which he kept, all express his wonder at the strange

sights, and all breathe the kindliness of nature and affection for

home and those at home which all his life long were strongly marked

characteristics. His letters to his mother are especially pleasing. He

was away for but little over eighteen months, yet an account of his

travels merits a chapter to itself. The commencement of 1813 marked an

epoch in his life, the close of the same year marked another.
